Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.
The answer is twenty-three percent (I had this question before)

3 Which of the following represents a function? A {(-2, 1), (-2, 0), (-2, 1), (-2, 2)} B {(-1,0), (0, 1), (1, 2), (2, 3)} C {(1,

Answer:
A
Step-by-step explanation:
because they want you to look for the number who repeat in the right like A (
3(3x-10)=5(x+10)
9x-30=5x+50
+30 +30
9x = 5x+80
-5x -5x
4x=80
/4 /4
x=20
